Sept. 7, 1929 A. F. BAILLY RETAINING DEVICE Filed March 29, 1928 l N V ENTO R Arikar Ifiaa'lfy BY ATTORN EY WITNESSES UNITED STATES ARTHUR r.BAILLY, or YABDVILLE, NEW J RSEY RETAINING DEVICE Application filedMarch 29, 1928. Serial No. 265,607.

This invention relates to means which may be employed for adjustably anddetaehably holding, and for forming a brace between relatively movablecomponent parts of an article, such as a folding chair, and which may beused in conjunction with parts of other articles to be held in dillerentadjusted positions or angular relationships with respect to each other.

The principal object of the present invention is the provision ofappurtenances characterized by novel and improved features, which coactor cooperate for the intended purposes, and which when in use, make itpossible to carry out adjusting, holding and bracing operations quicklyand easily.

The nature of the invention and its distinguishing features andadvantages will appear when the following specification is read I inconnection with the accompanying drawing, in which Figure 1 illustratesthe appurtenances of the present invention applied to a folding chair.

Fig. 2 is a sectional view taken on the line 2'2 of Fig. 1 on anenlarged scale.

Fig. 3 is a sectional view taken on the line 8-3 of Fig. 2.

. The appurtenances of the present invention are shown applied to afolding chair which is by way of example of one use of theseappurtenances, and it is to be understood that the appurtenances may beemployed in conjunction with other articles requiring adjustment orretainment of parts thereon.

In accordance with the present invention use is made of a plurality ofattachments 10, of similar construction, and each consisting of anelongated plate having a hole 11 therein and notches 12 arrangeddiametrically opposite each other, and each being opened to said hole11. The plate 10 is provided at each end with a hole for theaccommodation of a suitable fastening element such as a screw 13. Asuitable number of the plates 10 are secured to each side rail 14forming a part of a folding chair. Said rail 14 is provided with arecess 15 over which each plate 10 is secured.

Adapted to coact or cooperate with each of the attachments 10 is anappurtenance 16. The said appurtenance 16 includes an element consistingof rigidmembers 17 and 18, the former being much longer than the latter,and the said members 17 and 18 being hingedly connected together asat19, thus making a jointed element. One end of the appurtenance .16 isswivelly connected with a side rail 20 of the chair, the said rail 20being connected with the rail 14 hereinbefore referred to for relativemovement. The swivel connection in the present instance is produced bythe use of an attachment 21 consisting of an eye 22 and integralmelnber23. The eye 22 is connected as at 2 1 with the end of the PATENTOFFlC Ei member 17 and the member 23 extends through the rail 20,-and isprevented from being separated from the rail by a head and washer 25orany other means. It will now be understood that the appurtenance 16will have swingingmovement with respect to the attachment 21, and thatthe attachment21 will have turning movement withrespect to the rail 20.The appurtenance 16 also includes an interlocking device 26 which isdesigned to be engaged with any one of the at tachments 10. The device26 is carriedby the rigid member 18. The said device 26' includes a stud27 whichextends through a hole in the member 18, the said stud having atransverse pin which provides projecting ends 28, and said stud 27 alsohas a manipu lating knob 29. The stud 27 is under the in fiuence of aspring arranged between the member 18 and the knob29. a In theapplication of the appurtenances of the present invention, it will beapparent that, when it is desired to adjust the angular relationship ofthe parts constituting the chair shown in Fig. 1, and to hold the saidparts substantially braced, it is only necessary to swing theappurtenance 16 to a position so that the device 26 may be interlockedwith one of the attachments 10. Thisis accomplished by manipulating thestud 27 to bring the projecting ends28 respectively into the notches 12,then pressing on the knob 29 to bring the ends 28 within the recess 15.The knob 29 is then given a quarter turn, and is released, whereupon thespring 30 functions to bring the ends 28 of the pin into engage mentWith the attachment or plate 10. By making the appurtenance 16 ofjointed construction, it is possible to obtain the necessary 5 andproper disposition of the device 26 With respect to any particular oneof the attachments 10, it also being apparent that the swivel connectionprovided by the attachment 21 also makes it possible to obtain theproper angular position of the appurtenance 16 in its entirety.

By providing an attachment 10 on the rail 20 with which the appurtenance16 is connected, it is possible to detacha-bly hold the appurtenance 16in place when not in use as indicated in dot and dash lines inFig. 1.

It is to be understood that the invention is not restricted to theprecise arrangement of parts shown and described, as details of con 20struction may be modified and rearranged wit-l'iout departing from thespirit the in vention, the scope of which is limited only by the termsof the appended claim.

I claim:

The combination Withrelatively movable component parts of an article oi?a plurality I of similar attachments on one of said parts, an elementconsisting of rigid members hingedly connected together, means connectedWith one end of one of said rigid members I for swivelly connecting saidelement with one of said parts, and a device on one end of the otherrigid member, said device adapted to be detachabiy connected with anyone of said attachments to connect said parts together and to form abrace between said parts.
